Severe Plastic Deformation (SPD) techniques provide bulk materials with improved mechanical properties due to the ultrafine-grained (UFG) microstructures that can be achieved by this process. One of the most used and investigated methods of SPD is Equal-Channel Angular Pressing (ECAP). The deformation behaviour and characteristics of the material during the processing, have been researched with simulation software. The software contributes with the visual aid and the calculations of stress and strain. The information retrieved from simulations is necessary to complement experimental work and provide perspective in order to design the tools used in ECAP. This study presents a simulation of ECAP processing of commercial Ti-6Al-7Nb alloy.
